TECHNICAL FIELD

The present invention relates to a fluid dispenser comprising: a fluidreservoir; a fluid dispenser member that is connected to the reservoir;an actuator member for actuating the dispenser member; a fluid dispenserorifice that is connected to the dispenser member; and an applicationwall for applying the fluid coming from the dispenser orifice onto theskin. This dispenser, which can also be described as an applicator,finds an advantageous application in the fields of cosmetics andpharmacy, and more generally in the field of treating and caring for theskin.

BACKGROUND OF THE INVENTION

In the prior art, numerous dispensers already exist that are capable ofdispensing fluid, optionally in metered manner, for application to anapplication surface, such as the skin, the nails, the mucous membranes,the hair, etc. In general, the dispenser member is a pump or a valvethat may be actuated by means of a pusher on which pressure is exertedby means of one or more fingers. The fluid from a reservoir is put underpressure in the pump chamber or valve before being forced through adispenser orifice that is usually arranged in an application wall forcoming into contact with the skin. The application wall is used tospread the dispensed fluid over a greater or smaller area of the skin.

Naturally, the effectiveness of this skin treatment depends mainly onthe characteristics of the fluid that is applied, and on the quality ofits application. It also depends on the type and quality of the skin. Anobject of the present invention is to increase the effectiveness of theskin treatment by preparing the skin before applying the fluid. Anotherobject is to treat the skin while applying the fluid, and even afterapplying the fluid.

BRIEF SUMMARY OF THE INVENTION

To do this, the present invention proposes that the dispenser furthercomprises at least one source of radiation, such as a light-emittingdiode (LED), emitting monochromatic light in the spectrum lying in therange 400 nanometers (nm) to 700 nm, and having an anti-inflammatoryaction and/or a stimulating action for stimulating skin-regenerationmetabolisms.

This type of light is already used in institutes for combatinginflammation, boosting collagen synthesis, improving vascularization,accelerating the repair of stretch marks or scar tissue, and also forreducing pain. Thus, it is already known to subject the skin toradiation that is pure in color or “monochromatic”, in the range blue tored. However, it is especially the red and the near infrared thatprovide such performance. Infrared light is thermal radiation at awavelength of about 700 nm or longer. The light heats the area beingtreated, stimulates blood circulation, heats tissues, and activatesfibroblasts. With regard to red light, it mainly stimulates metabolismsfor regenerating the skin by producing new collagen: this is referred toas collagen neosynthesis. In order to generate such light, it ispossible to use LEDs or low power lasers in low level laser therapy(LLT).

The present invention specifically makes provision for associating orcombining a conventional dispenser/applicator with one or more sourcesof radiation of this type for the purpose of treating the skin before,during, and/or after applying the fluid. The effectiveness of the fluidis thus optimized by acting on the quality of the skin. US2007/185553and US2007/198004 describe such devices for a therapeutic purpose. Theergonomics and shape of the devices are not adapted to an individualutilization for cosmetics application.

In order to overcome the problems of the prior art devices, the presentinvention proposes a fluid dispenser comprising:

-   -   a fluid reservoir; and    -   a body receiving:        -   a fluid dispenser member that is connected to the reservoir;        -   an actuator member for actuating the dispenser member;    -   a dispenser and diffuser head forming a fluid dispenser orifice        that is connected to the dispenser member, and an application        wall for applying the fluid coming from the dispenser orifice        onto the skin;    -   a module comprising at least one source of radiation, such as an        LED, each emitting monochromatic light in the spectrum lying in        the range 400 nm to 700 nm, and having an anti-inflammatory        action and/or a stimulating action for stimulating        skin-regeneration metabolisms;    -   the dispenser and diffuser head comprising a source housing, and        in that the body comprises a module housing wherein the module        is received, this module housing communicating with the source        housing so that the source of radiation extends in the source        housing of the head.

Thus, the dispenser has a compact shape. Advantageously, the module isreceived in a removable manner within the module housing. According to apractical embodiment, the module is integral with the dispenser anddiffuser head, thus forming together an integral unit which is receivedin a removable manner on and within the body. According to anotherfeature, the body has a horizontal cross-section of oblong shape wherethe dispenser member, the actuator member and the module housing withthe module are arranged, the dispenser member being advantageouslyarranged between the actuator member and the module housing, theactuator member being arranged at a part of greatest curvature of thebody. Preferably, the dispenser presents the general shape of a pen,with the body arranged between the dispenser and diffuser head and thereservoir.

The dispenser of the invention mat thus be easily handled as a pen by auser for a personal application, namely at the face.

Advantageously, the source of radiation may emit red light at about 660nm.

According to another advantageous characteristic, the source ofradiation may emit light from the application wall. Preferably, thesource of radiation emits light through the application wall.Advantageously, at least locally, the application wall is made out of amaterial that is transparent and/or translucent to the light emitted bythe source of radiation, the source emitting light through said materialtowards the skin. Preferably, the application wall guides or conveys thelight emitted by the source of radiation. Thus, the application wallperforms two functions, namely a first function of transmitting/guidingthe light coming from the source of radiation, and a more conventionalsecond function of applying/spreading the dispensed fluid. The fact ofusing the application wall to guide or convey the light is acharacteristic that is particularly advantageous. Another advantage thatis inherent to this embodiment resides in the fact that the distancebetween the light source and the skin is constant and unvarying, sinceit is determined by the application wall that is itself at a determinedand unvarying distance relative to the light source. It is thus possibleto determine, with accuracy, the length of time during which the skin isirradiated or illuminated, as a function of the power of the emittedlight, of the distance between the light source and the applicationwall, and of the diffusing qualities and characteristics of theapplication wall. Thus, it suffices for the user to be exposed to thelight only once in order to guarantee the desired effect. In addition,because the light is emitted through the application wall, thisnecessarily implies that the fluid is separated from the light source bythe application wall, such that the light source cannot be soiled withfluid in any way.

In another advantageous aspect of the invention, the dispenser orificeopens out to the application wall with a direction that is substantiallyparallel to the direction of the light emitted by the source ofradiation. This implies that the fluid may be dispensed and applied tothe skin directly after the exposure-to-light stage, withoutmanipulating the dispenser other than by pressing on the actuatormember. In other words, the exposure-to-light and the fluiddispensing/application stages may take place while the dispenser isbeing held in a single and determined orientation.

According to another particularly advantageous characteristic of thepresent invention, the dispenser further includes power supply means forpowering the source of radiation, which means are activated only whenthe application wall is in contact with the skin Advantageously, theapplication wall causes a switch to operate so as to trigger theactivation of the power supply means for powering the source ofradiation. This means that the light is emitted only when the skin is ata distance that is predetermined by the distance between the applicationwall and the source of radiation. As a result, it is impossible toirradiate, deliberately or accidentally, sensitive organs such as theeyes. Applying the application wall to an eye is unlikely. It ispossible to use any known prior-art technique for using the applicationwall as a switch for triggering the activation of the power supply forpowering the source of radiation. By way of example, provision may bemade to move the application wall a little, like a mechanical switch.The application wall may also be used as a contact element that issensitive to heat, touch, presence, etc.

In a practical embodiment, the application wall is formed by a dispenserand transmitter head that includes a source housing for receiving thesource of radiation. Thus, the source of radiation is completelyprotected in its housing. It cannot be damaged or contaminated.

In another advantageous aspect of the invention, the actuator member ismovable in an actuation direction that is substantially perpendicular toa direction for dispensing the fluid through the dispenser orifice.Thus, the dispenser may be taken hold of and used like a pen, pressinglaterally on the actuator member by means of the index finger, whichmakes it possible to hold the dispenser with great accuracy.

In another practical aspect of the invention, the source of radiationforms part of a module that further includes electronic circuitry, powersupply means, activator means for activating the power supply means, anda timer. The activator means that trigger the power supply means mayinclude a sensor that is sensitive to pressure, contact, presence, orheat, or they may even be in the form of an electric contactor.

In a practical embodiment, the reservoir is in the form of a removableand replaceable cartridge that is arranged in a casing that isconnected, in removable manner, to a body that receives the dispensermember, the actuator member, and a dispenser head that forms thedispenser orifice, the application wall, and a source housing receivingthe source of radiation. The dispenser thus comprises two distinctsub-assemblies, namely a lower sub-assembly that is constituted by thereservoir and the casing, and an upper sub-assembly that is constitutedby the body, the dispenser member, the actuator member, the dispenserhead, the module, and optionally a cap that comes to cover theapplication wall.

The spirit of the invention resides in the fact of incorporating, in asingle dispenser, one or more sources of radiation capable of treatingthe skin, and an applicator capable of spreading a fluid on the skin.The compact configuration and the ergonomic shape, comparable to a pen,allow an easy utilization.

DETAILED DESCRIPTION

Reference is made to FIGS. 1 to 3 taken together in order to describe indetail the structure and the operation of a dispenser in a non-limitingembodiment of the invention.

The dispenser comprises: a fluid reservoir 1; a casing 2 in which thereservoir 1 is received; a dispenser member 3, specifically a pump; anactuator member 4 for actuating the pump 3, and that is specificallyincorporated in the pump; a module 5 that is provided with one (or more)sources of radiation 51; a body 6 that receives the pump 3, the actuatormember 4, and the module 5; and finally a dispenser head 7 that ismounted on the body 6. Optionally, the dispenser may also include aprotective cap 8 that covers the dispenser head 7. With the exception ofthe module 5, all of the component elements of the dispenser may be madeby injection-molding plastics material. The dispenser is shownapproximately life-size in FIG. 1. It should be observed that thedispenser is not circularly symmetrical, but generally convexunilaterally towards the module 5. The dispenser is intended to be takenhold of like a pen, with the convex portion oriented towards the palm ofthe hand, and the actuator member 4 being intended to come into contactwith the index finger. In FIG. 2, it should be observed that the topportion of the casing 2 and the body 6 present a horizontalcross-section of elongate shape that is oblong or egg-shaped. Theactuator member 4 is advantageously arranged at a part of greatestcurvature of the body 6. The dispenser thus presents a configurationthat is narrower in one direction than in the other, thereby making iteasier to hold it in the hand like a pen. Intuitively, the user takeshold of the dispenser in such a manner as to position the actuatormember 4 under the index finger. The dispenser is held mainly betweenthe thumb and the middle finger at the body 6, on either side of themodule 5 and the actuator member 4.

The fluid reservoir 1 may be made with a section that iscircularly-cylindrical, constituting a cylinder 11 slidably receiving afollower piston 13. In order to prevent any suction in the cylinderbelow the follower piston 13, the cylinder is provided with a vent hole12. At its top end, the cylinder 11 is provided with a fastener ring 14that is provided with an internal thread 15. In entirely conventionalmanner, the follower-piston 13 moves inside the cylinder 11 as fluid isextracted therefrom. Thus, air never penetrates inside the reservoir 1.This is a particular and non-limiting embodiment: any other reservoir,with or without air inlet, can be used in the present invention.

The reservoir 1 is arranged inside the casing 2, the main function ofwhich is to protect and mask the reservoir 1. As mentioned above, itshould be observed that the casing 2 presents a complex geometricalshape, with a top portion of horizontal cross-section that is oblong oregg-shaped. However, the casing 2 internally defines a housing foraxially receiving the reservoir 1. It can thus be said that the casing 2forms a unilateral projection that extends on one side only of thereservoir 1, as can be seen in FIGS. 1 and 3. The casing 2 includes anopening edge 26 for coming into engagement with the body 6 as describedbelow.

The dispenser member 3, specifically a pump, comprises a pump body 31that defines a pump chamber 32 that, at its bottom portion, communicateswith the reservoir 1 through an inlet valve 33, and that, at its topportion, is provided with an outlet valve 34. The pump 3 is of aparticular type, specifically a “diaphragm” pump, given that theactuator member 4 is in the form of a flexible actuator wall thatadvantageously forms an integral part of the pump body 3. By pressing bymeans of finger, e.g. the index finger, on the deformable wall 4, theworking volume of the pump chamber 32 is reduced, and this puts thefluid that it contains under pressure, closes the inlet valve 33, andopens the outlet valve 34 through which the fluid under pressure isforced. A pump of that type and its operation are known in the field of“diaphragm” pumps. The particular structure of the pump 3 is notcritical to the present invention: another type of pump could be usedwithout going beyond the invention.

The pump 3 with its actuator member 4 are incorporated in the body 6that, by way of example, may be overmolded onto the pump 3 and itsactuator member 4. The body 6 forms an assembly bushing 61 that isexternally threaded so that the internal thread 15 of the ring 14 maycome into engagement therewith, so as to connect the opening of thereservoir 1 to the inlet of the pump where the inlet valve 33 issituated. Another type of assembly, e.g. a snap-fastening or a bayonetfastening, may also be used to connect the reservoir 1 to the body 6, ormore generally to the inlet of the pump 3. In the invention, it ispreferable for the reservoir 1 to be connected to the body 6 inremovable manner, so that it may be replaced like a cartridge. To thisend, it should be observed that, at its opening edge 26, the casing 2 issnap-fastened to a flange 62 that is formed at the bottom end of thebody 6. In order to replace the reservoir 1 once it is empty, itsuffices to separate the casing 2 from the body 6, and to unscrew thereservoir 1 from the threaded bushing 61 of the body 6. By way ofexample, provision may be made for the opening of the reservoir 1 to beclosed initially by a film that is pierced by some member that issecured to the body 6 or to the inlet valve 33, while the reservoir 1 isbeing screw-fastened on the threaded bushing 61. It is then possible todefine two sub-assemblies, namely a lower sub-assembly that isconstituted by the reservoir 1 and the casing 2, and an uppersub-assembly that is constituted by the body 6 and all of the componentelements that are mounted thereon.

At the outlet of the outlet valve 34, the body 6 forms an outlet chimney67 that leads to the dispenser orifice 73, as described below. The body6 also defines a module housing 65 inside which the module 5 isreceived. The body 6 forms a first slot 63 through which the lightsource 51 extends, e.g. a source in the form of one or more LEDs. Thebody 6 defines a second slot 64 having a function that is explainedbelow.

The dispenser and applicator head 7 is an asymmetrical part that may bemade by injection-molding a plastics material that is transparent ortranslucent. The head 7 includes an outlet tube 71 that internallydefines an outlet channel 72 that connects the outlet chimney 67 to thedispenser orifice 73. By way of example, the outlet tube 71 may beforce-fitted in the chimney 67. The head 7 also includes an applicationwall 74 into which the dispenser orifice 73 opens out. In the embodimentin the figures, the application wall 74 extends mainly on the righthandside of the dispenser orifice 73, defining a curved slope. It should beobserved that the application wall 74 presents extra thickness thatserves as a light waveguide 77, as described below. The extra thicknessforming a wave guide 77 defines a source housing 78 for receiving thesource(s) of radiation 51. The head 7 also includes a peripheralstabilizing lip 76, so as to ensure that the head 7 is held stationaryon the body 6 in stable and permanent manner. The head 7 also includes atransmission pin or tab 75 that extends through the second slot 64 so asto be capable of penetrating into the module housing 65. The applicationwall 74 is made, at least in part or locally, out of a material that istransparent or translucent to visible light and to infrared. By way ofexample, it is possible to use copolyesters or styrenes to make theapplication wall, and even the head 7 as a whole.

It should already be understood that it is possible to dispense fluidthrough the dispenser orifice 73 at the application surface 74 byactuating the actuator member 4 of the dispenser member 3 that makes itpossible to take the fluid from the reservoir 1, to put it underpressure in the chamber 32, and to force it through the outlet valve 34,the chimney 67, and the outlet duct 72, until it reaches the dispenserorifice 73. Once the dispensed fluid is present on the application wall74, the user may apply it and spread it over an application surface,such as the skin. The dispensed fluid is preferably a viscous fluid,such as a cream, a gel, a pomade, etc.

The module 5 is an electronic module that is provided with one or moresource(s) of radiation 51 in the form of one or more LEDs, for example.Each LED emits monochromatic light. By way of example, it is possible toprovide a blue LED and/or a red LED. The module 5 may be in the form ofa small case that has one or two LEDs on top. The module comprises:power supply means 53, e.g. in the form of a battery; electroniccircuitry 52, e.g. in the form of a small printed circuit card;activator means 54 for triggering the powering of the source 51 by thepower supply means 53; and a timer 55 that determines the length of timethat the light source 51 is powered. In other words, the activator means54 determine the start of the stage during which the light source 51 ispowered, and the timer 55 determines the end of that stage. Naturally,the module 5 may also incorporate other electronic components that arecapable of performing other functions. The module 5 is arranged and heldinside the module housing 65 that is formed by the body 6. In thismounted position, the light source 51 extends through the first slot 63of the body 6 into a source housing 78 that is defined inside thedispenser head 7. A large portion of the source housing 78 is formed bythe application wall 74 that is made out of a material that istransparent or translucent to the light emitted by the source ofradiation 51. To this end, the light emitted by the source 51 may be ina spectrum lying in the ultraviolet to infrared range of 400 nm to 700nm. By way of example, it is possible to use a red light having awavelength that is about 660 nm. Skin that is exposed to such a lightis, amongst other things, subjected to stimulation of its metabolismsregenerating skin, and produces collagen. Thus, the light is emittedinto the source housing 78, is guided by the extra thickness forming awaveguide 77, and then exits the application wall 74 so as to reach theskin that is in contact with the application surface 74. Preferably, thetransparent or translucent material that constitutes the applicationwall 74 diffuses in all directions the light that passes therethrough,in such a manner as to make the distribution of light uniform over thesurface of the skin. When the head 7 is made entirely out of such adiffusing material, all of the component elements of the head, includingthe outlet tube 71, may serve as waves to guide and transmit.

In addition, the transmission pin 75 extends from the applicationsurface 74, through the second slot 64, and into the module housing 65,so as to co-operate directly or indirectly with the activator means 54.The transmission pin 75 serves as a conducting or transmitting guideenabling information to be passed from the application wall 74 to themodule 5. By way of example, provision may be made for the pin 75 to becapable of transmitting a thrust force to the activator means 54, whichthrust force is exerted on the application surface 74. In thisconfiguration, the activator means 54 may comprise a thrust detector, ormerely an electric contactor that is sensitive to thrust. When theactivator means 54 perceive pressure, they trigger the electric poweringof the light source 51. Provision may also be made for the transmissionpin 75 to be adapted to transmit heat, contact with another element, orthe absence of light. It is also possible to provide other transmissionmeans, such as electrical, thermal, or optical conductors. In theseconfigurations, provision can be made for the activator means 54 tocomprise a heat, presence, or absence-of-light sensor. It is alsopossible to provide an electronic contactor at the application wall 74.In the prior-art, numerous techniques exist for transmitting informationto activator means. In the present invention, the object is to activatethe light source 51 only when the application wall 74 is in contact withthe skin. Such contact with the skin creates pressure, heattransmission, an electric current, and/or darkening of the applicationwall: one or more or these parameters can be transmitted by means of thetransmission pin 75 to the module 5 so that it triggers powering of thelight source 51. Any triggering that is accidental or damaging to healthis thus avoided. After activation, the source of radiation 51 remainspowered for a length of time that is predetermined by the timer 55,which predetermined length of time enables the area of skin to which thefluid is applied to be treated adequately. However, when the wall is nolonger in contact with the skin, the power should be switched off,thereby interrupting the timer so as to avoid accidental irradiation.When the applicator is briefly lifted off the skin, provision may alsobe made for the timing by the timer merely to be suspended and notreinitialized.

It should be observed that the distance between the light source 51 andthe skin is determined by the application surface 74 against which theskin comes into contact. It is thus possible to determine, withaccuracy, the power of the light source 51, its distance to theapplication surface 74, and the length of time during which it isactivated in order to obtain the desired skin treatment. In addition,given that the light source 51 is arranged under the application wall74, it need not come into direct contact with the fluid: it thus cannotbe soiled by said fluid.

It should also be observed that in the event of failure ormalfunctioning, the module 5 can easily be removed from its housing 65so as to be replaced by a new module. The module 5 is thus merely in theform of a refill. It is also possible to remove the module 5 from itshousing 65 merely so as to replace or recharge the power supply means53.

Given that the application surface 54 can easily be cleaned, it isguaranteed that the skin is exposed in constant and reproducible mannerto the light from the source of radiation 51.

FIG. 4 represents an alternative embodiment wherein the head 7 and themodule 5 form together an integral unit U which is mounted on the body6. The unit U is represented when being mounted or removed in FIG. 4.The module is already inserted through the unique window 66 whichpermits access to the module housing 65. The outlet tube 71 is alignedwith the outlet chimney 67.

By means of the invention, the effectiveness of a conventionaldispenser/applicator is considerably improved by the prior,simultaneous, and/or subsequent treatment of the area of skin by meansof appropriate light.
